Compensated Guitar Nut for Electric

It arrived to Europe, and It works. On my guitar works as it is no need for a shim. I use it on 7 string to compensate for the first 6 strings for chords. I hope one day there will be 7 string and bass version.

These work great and keep your open chords sounding perfect. You will not hear dissonance where it doesn't belong, and you will be very happy with the sound of your guitar after putting this on. The only issue with the SOS system is that they are a bit thin, and you will have to file your nut to get a proper grip on the SOS with the strings. I put these on four of my Les Pauls and I had to file the nut on each guitar to get a perfect fit. I have files, so I didn't have a problem with this, but many people don't have nut files. If you need nut files, be sure to get them in your preferred gauge, as they are specific to string gauge. I use Hiroshima files and highly recommend them, but there are many brands out there.

Great idea and simply to fit! Thank you so much!

I bought this for my new Fender Strat and it works like a dream! The compensation amounts for the different strings are proportional to how sharp each of them sounds on the first few frets, so the G-string and low E-string get the most compensation. It is necessary to re-intonate the octaves at the 12th fret after installation, but that is all you need to do. Cowboy chords now sound in tune with each other! One thing to consider with all the various versions of this device is that they only work on guitars which have the nut in the mathematically correct "zero fret" location. This includes all Fenders, Gibsons, and most mass-produced classical guitars. However, I discovered that installing the acoustic guitar version on my Takamine G-series 6-string acoustic was not satisfactory as this guitar, in common with all recent Takamines, has around 0.7 mm cut off the end of the fretboard already to improve intonation on the lower frets. I solved the problem myself by making a proper compensated nut out of a stock G-series one, taking into account the existing fretboard compensation. I also had a new saddle made with the resulting altered bridge compensations in place (more of an in-line shape). This device is based on some sound physics research and there is a visor/shelf nut made by Minehara in Japan that uses the same compensation amounts. All this evidence and my own experience so far indicates that the Earvana compensated nuts use the wrong amounts for the bass strings (they compensate the D-string more than the low E, which makes no sense as the E string goes sharper when fretted on frets 1-3 than the D-string), although the top three strings seem to have the correct amounts. The compensated nut used on Ernie Ball Musicman guitars follows the same pattern as the Hosco device. Lastly, I have successfully used the Ukulele version of the S.O.S. on a Kala soprano uke and found that it improved the octaves at the 12th fret as well, which were a little sharp before installation. I would highly recommend this product until more guitars start to appear with proper compensated nuts installed as standard, particularly for use on electric guitars, classical guitars and ukuleles.
